1st go to http://babelfish.altavista.com/babelfish/tr for page translation and enter:- http://www.langzeittest.de/opel-zafira/index.php
This German web site is dedicated to the Zafira model and once translated by bablefish has photos etc. Select the technical section then from the list on the left hand side under 'door lining'. Give details and photos from removing the door speaker grills to switches etc.
